The Long Count

A Mayan prophecy seems to specify 21st December 2012 as the end of a 'Long Count' and the beginning of a cataclysm that will engulf us all. Assorted spiritualists and new age groups add their own spin on the day's events: some say we are passing a tipping point, the birth of a new age where we'll take better care of our people and our planet; others say we are entering the end times, where many will die and the chosen few will ascend to another dimension, a higher consciousness - in a space ship.

Avis Roberts, a journalist, has been following one such group and, today, he is joining them at Silbury Hill in Wiltshire to share their final moments and figure out what is actually happening.
